Numerical Computation of Two-Phase Flow in Porous Media
Published in 2013
In this study we investigate the heat and mass transfer in a porous media with phase change. The liquid fluid is injected from one side and heated from the other side, where it leaves the porous material in a gaseous state. Dominant forces are capillary interactions and two-phase heat conduction. To model the process we use a two-phase mixture model on a macroscopic scale. This model is presented in two versions. The first version is a one-equation model for energy conservation, while the second is a two-equation model. The versions are implemented in COMSOL Multiphysics® and then compared with other results in the literature. A parameter study is done for the second model.
